Fix a video that came out sideways or upside down, or flip a mirrored selfie. The new copy is made on your own device.
It plays in a preview so you can see which way it is facing now.
Turn it a quarter either way, turn it upside down, or mirror it left to right or top to bottom.
The video is encoded again as an MP4 with the new direction built in.
A phone often records the picture in its natural landscape shape and adds a small note saying which way up it should be shown. Some players and websites ignore that note, so the same file looks right in one place and sideways in another.
Turning it here changes the picture itself, so it looks the same everywhere. That means the video has to be encoded again, which takes a while in the browser and costs a very small amount of quality, so the original is worth keeping.
Mirroring is useful for front camera videos, where text and signs come out back to front. Flipping left to right puts them the right way round.
No. The work happens inside this tab, on your own machine. Open your browser's network tab while you use the tool, there is no request carrying your file.
None set by us. Very large files are limited only by your device's memory, and we warn you before that becomes a problem.
No, and there is no daily limit either. There is nothing to sign up for.
Yes. The sound is carried over to the new copy.
That only changes how that one player shows it. This changes the video itself, so it looks right wherever you send it.
Very slightly, because the video is encoded again at a high setting.
